Thanos Vs Beerus

* They both take antagonistic roles in big movies (Battle of Gods and Infinity War) where they are so strong, they even beat the main team of heroes (the Z Fighters and The Avengers) who have beat massive threats in the past, even with some gaining a big powerup (Goku getting Super Saiyan God and Thor getting Stormbreaker)
* They also both beat a prideful, alien, warrior prince who despite being one of the strongest beings in their respective stories, get stomped out with little to no difficulty, even after having increased power from the last time their teams last saw them (Vegeta having surpassed Goku and Thor having awakened)
* In said movie they travel across different planets fighting each hero, regardless of where they are
* They both see themselves as necessary evils, destroying planet after planet for the good of the universe
* They are both distinguished by gold items they wear (The Earing for a God of Destruction and The Infinity Gauntlet)
* They both die in alternate timelines through a method the heroes of the main timeline never used (Killing the Kaioshin and using the Book of Vishanti)
* They are both capable of effortlessly killing anyone through a method that very little other characters in the series can do (Hakai and a snap of Thanos’ fingers)
* They both kill gods associated with the colour green with minimal effort (Zamasu and Loki) who contrast (Zamasu went from being a good person to an evil one and Loki went from being a villain to a hero). These two gods also have alternate versions of themselves from other timelines who are known for time travel
* They both search across the universe for a cosmic power (A fight with a Super Saiyan God and the Infinity Stones) and are successful in their pursuit
* They form alliances with other Alien Villains - known for conquering other planets, who are defeated by the heroes (Frieza and Ronan the Accuser), despite them even gaining unfathomable power (A Golden Form and The Power Stone)
* They are both considered Gods in contrasting ways (Beerus literally being a God While Thanos was born to a “God-Like” Race)
* They have multiple helpers (or subjects) to help further help with their goals (The Oracle Fish and Whis and the Black Order), however they also contrast (Whis is stronger than Beerus and remains impartial to everything while the Black order are directly under Thanos’ command and are much weaker than him)
* They both have points in the series where they interact with the child version of two powerful villains turned heroes (Vegeta and Gamora) - both of whom have bad memories with them due to their actions with their planet and it’s people (Vegeta resented the fact his Father, King Vegeta could only submit to Beerus’ power. Later on beerus is also the reason Vegeta’s entire planet blew up while Gamora’s planet had half of it’s population wiped out by Thanos). Despite this, they both train under Beerus and Thanos at some point
* They both have moments of trying to make their opponent attack them, only to completely destroy them afterwards
* They also both fight extremely powerful fighters, known for transforming with age and beat them with just their fists (Vegeta and Hulk)
* They both fight and beat Very Intelligent combatants who have had their fathers die (Son Gohan and Iron Man)
* They both have fights with family members in contrasting scenarios (Beerus and Champa are brothers who are on par with each other and often fight over nothing while Gamoura is thanos’ adopted child who tried killing him, only to get stomped)
* They contrast after their main fight with the heroes (Beerus became on good terms with Goku and Gang while Thanos was killed in his home)
* Both have had extreme presence within their respective stories, altering them entirely just due to their power and actions (Beerus being a pinnacle of power, being behind the destruction of planet vegeta, giving Goku and Vegeta access to god ki and being the reason that Goku eventually meets Zeno while Thanos killed countless people across the universe and after the snap caused effects which everyone felt for decades after) including a behind the scenes presence (Beerus ordering Frieza to do things and destroying things centuries and sealing elder kai away and Thanos conquering worlds for decades and ordering other villains such as Loki to do things)
* They also both travel to another dimension in search for their goal (King Kai’s Planet and Planet Volmir)

### Fight Potential

Obviously, this fight would occur just after the events of infinity war. After thanos kills half of the universe's population, Whis would awake Beerus, due to this emergancy, and beerus and whis would travel to the planet thanos is on in order to fix things (This would obviously be before thanos destroys the gauntlet). Regardless, the fight could get really creative, with Thanos warping space, time and reality in order to get the upperhand on beerus, with beerus erasing any potent threats that came near him. You can also display his experience and intelligence when it comes to Thanos warping time and space in order to get the better of thanos. You can have thanos' mind stone be used to try and attack Beerus' mind, and while it does fail it gives thanos an opening for a big attack. Beerus can active lower forms of ultra instinct in the fight as well (since he has in the manga) in order to avoid attacks coming at him due to the warped reality. You can have them both travel across dimensions as they fight, breaking and threatening all of reality while they do so in order to add scale to the fight. I also picture this fun interaction towards the beginning of the fight, where Beerus finger flicks thanos so far he crashes on a nearby moon - thanos would then throw the moon at beerus similar to how he did in infinity war, and beerus would hakai it - only for Thanos to land a big hit while beerus is destroying it. The fight ends with either thanos towering over beerus, as he snaps his fingers and beerus disappears from existence or Beerus erases the infinity gauntlet itself, before taking thanos to his knees and erasing him
