Mount Aku (Aku Realm)/Invasion

The Mount Aku Invasion is a special stage that appears in Mount Aku after clearing all Aku Realm stages. It introduces a new enemy, Lord of Ruin Jagando.
Upon completion, Jagando Jr. will be unlocked, a Platinum Ticket is awarded, and the Aku Altar will permanently lose its ability to disable +levels, being replaced in any other stages with the Inactive Aku Altar.
==Battleground==
*The enemy base here is an Aku Altar.
*1 Lord of Ruin Jagando spawns as the boss after 6.67 seconds200f.
*3 Fallen Bears spawn after 16.67 seconds500f, delay 93.33~96.67 seconds2,800f~2,900f.
*Infinite Cerberus Kids spawn after 16.67 seconds500f, delay 23.33~30 seconds700f~900f.
*3 Condemned Pengs spawn after 56.67 seconds1,700f, delay 83.33~90 seconds2,500f~2,700f.
*Infinite Condemned Pengs spawn after 240 seconds7,200f, delay 83.33~90 seconds2,500f~2,700f.
*When the base reaches 75% HP:
**5 Cerberus Kids spawn, delay 2 seconds60f.
**1 Fallen Bear spawns.
==Strategy==
Since the difficulty of the stage is determined not just by your units, but also by luck of Death Surge/Jagando surges not spawning on your main units and your Shield Piercers' procs, you aren't always guaranteed to win this stage. However, units with surge immune/100% Shield Piercing will work better than others, as you won't need to rely too much on luck using them.
Before tackling this stage, ensure that you at least have these four units in your line-up; Crazed Cat (non-True Form so their speed is equal to Manic Eraser, level doesn't matter), Manic Eraser Cat (Lv50), Aku Researcher (LvAny), and Manic King Dragon (Lv50), as well as the Rich Cat and Sniper the Cat Battle Items. Bringing Eraser/Dragon below Lv50 will only add further difficulty to an already highly luck dependent stage, as Lv50 Eraser just barely survives Jagando's surges while Lv50 Dragon barely survives a hit/aftermath from Fallen Bear.
With these units and battle items in hand, you are now technically capable of defeating the invasion, albeit extremely unlikely. You can also automate attempts with these four units by bringing a Cat CPU. Simply turn off Cat CPU, wait until the boss wave, summon Crazed Cat, wait one second (or until Crazed Cat's recharge meter is half full) before summoning Manic Eraser Cat, then turn on Cat CPU and wait until RNG determines whether you win or lose.
Your odds of killing each Fallen Bear before the next arrives (and before Jagando reaches striking distance of your base) can be improved with Cat Researcher (true form of Aku Researcher), as his very fast attack rate alongside his high range allows him to get hits easily on Fallen Bear and Jagando aswell, provided you time him well to not get killed by a stray Surge.
When all three Fallen Bears are defeated, turn off Cat CPU but continue summoning Crazed Cat and Manic Eraser one second apart, as well as Manic King Dragon. Only summon Aku Researchers while Jagando is alone and his Shield is still active.
Other useful units and Cat Combos will be listed below, but keep in mind adding them to the existing lineup will effectively remove Cat CPU as an option.
Attack Up Cat Combos like Cool Japan, Sister Act or Brave Cutter can speed up the end of the stage where you are left slowly chipping away at Jagando until he dies after the support is exhausted.
===Recommended Units===
*Stone Cat (Lv30+) can be very useful in stalling Jagando if aided by Research Combos (3x Sm, M+Sm or L). Its massive health, immunities (meaning Condemned Peng can't slow it), high speed and relatively low cost can allow it to reliably delay Jagando by forcing him into attacking, whist preventing the surge from spawning if timed well. It also gives your other units (particularly shield piercers) a much better shot on the Fallen Bears by destroying any Cerberus Kids that happen to be obstructive. When the support dies out, it alone can practically pin Jagando indefinitely.
*Supercar Cat's 100% Shield Pierce and Knockback versus Traited enemies makes it a great choice against Jagando and Fallen Bear by destroying their Shields and recovering ground, although timing is required for it to actually get a hit in.
*Neo Cutter Cat (Lv49+) can be used to knockback Condemned Peng in one hit assuming Brave Cutter (which they are a member of) is active and they've strengthened after surviving a lethal strike. However, due to Condemned Peng's 50% slow chance as well as Jagando's constant attacks, there's no guarantee they will actually deliver.
*Maglev Cat (Lv50, with Attack Up Small) or Bullet Train Cat (Lv46) can also be used to deal enough damage to knockback Condemned Peng in one hit. Not only that, but if they land the killing blow, they can provide you with a cash boost well exceeding their summon cost. Just hope that they don't get slowed or sniped before they get there.
*Awakened Bahamut Cat (Lv30+) Can be used to take 2 kbs from Fallen Bear, skipping one Shield regeneration. Not only that, but Maglev Cat can also be used to deliver the third and final KB on the fallen bear, granting a huge cash boost. He can also be used during the final part of the stage to chip Jagando and take out the Condemned Pengs. He requires precise timing though, as Fallen Bear will always destroy him in a single hit.
*Cat Cactus (Lv36+) essentially trivializes the stage if you could afford the extreme evolution cost. Being strong against Aku enemies, immune to surges and with decent stats against them, it holds the threats rather well with its singular knockback.
*Metal Macho (Lv20) is good to have as despite his very long cooldown, he requires a specified amount of hits to kill, whereas your regular meatshields could be destroyed easily.
===Recommended Ubers===
*Summoner Satoru - An Anti-Aku LD CC specialist with Surge Immunity, Satoru is able to slow Aku threats and has a 20% chance to destroy their Shields. In True Form, he only gets better with 100% chance to cause knockback and 50% chance to destroy Shields. While Satoru wouldn't trivialize the stage, his lower cost and cooldown makes him disposable, and when backed by adequate support he can make matters much easier.
*Divine Kai - Kai is admittedly only useful with her Shield Piercing talent fully upgraded, as that's when her disposability and bulk for a tank comes into use. At level 39 or above, Kai can nuke a Fallen Bear in a single attack if her hit connects, allowing the player to focus on stalling Jagando and killing Condemned Pengs until the next Fallen Bear spawns during which Kai's fast recharge allows you to replace her easily. If Kai is leveled up further, she will assuredly survive long enough after killing a Fallen Bear that she can destroy Jagando's shield as well, making it that much easier to stall him. Just make sure Cerberus Kids, Condemned Pengs, or Jagando himself don't block Kai's path to the Fallen Bears and cause her to waste her attack, otherwise she will likely die before getting a second chance.
*Hevijak - Hevijak has has 50% shield pierce, knockback and resist vs Aku enemies. While he cannot outrange Jagando's Omni Strike, Hevijak can avoid his attacks while dealing with the Condemned Pengs and Fallen Bears. His resistance to Aku enemies allow him to tank their surges. His knockback ability can also recover lost ground if it hits and activates, especially in his True Form with the 100% knockback chance. However, due to his slow attack rate, he works best when backed by other anti-shield units to ensure he actually knocks back the main threats.
*Iz the Lady of Mourning - With Surge Immunity, 100% chance to destroy Shields and Omni Strikes hitting up to 350, this unit can be surprisingly useful just for getting around the Bears and Jagando quickly. However, her somewhat low health, range and two knockbacks mean she can be rather inconsistent in practice.
*Divine Lilin π - A somewhat useful Anti-Aku specialist, Lilin is strong against them, with 100% chance to destroy Shields and generate Surge Attacks. She can outrange Fallen Bear, and her Surge can also snipe enemies she may be unable to hit directly, specifically Jagando. Her short CD also helps, allowing her to be easily replaced even if lost.
*Malevolent Mad-Duck - Malevolent Mad-Duck is a target only unit that hits Red and Aku only, but boasts massive stats and Surge Immunity at high range. Given all threats are within his target traits, he can put his sheer strength to good use. He won't be able to outrange Jagando and still can't get around Shields, but he's handy to with how dangerous Fallen Bears can get.
*King of Destiny Phonoa - with Massive Damage to Traited, Surge Immunity, and 600 range plus Long Distance attacks, Phonoa stands out as a near perfect option for this stage. While they can't pierce shields, they are able to deal lots of damage to them, and can snipe pesky Fallen Bears and Condemmed Pengs that hide behind Jagando, isolating him with terrifying ease. The only thing that holds them back is their low health, so a strong frontline must be maintained for them to stay alive.
*Obliterator Diabolosa - outranging Jagando by 25 range with Massive Damage being able to deal 100k damage in one spot this unit makes this stage easy. Just do not forget to bring a Shield Piercer.
