Narrative: This involves 3 near misses and being cutoff by the same pilot three times. I was at 5;500 feet with flight following coming south to north to reach ZZZ Airport from the ZZZ VOR. The wind was out of the north and the runway in use was Runway XX. As I was descending to fly past the airport and join the pattern with a 45 degree entry to downwind; I heard at least 3 planes in the pattern. Then; I heard a Bonanza behind me announce a straight in. I advised him that it was unwise given a full pattern; which would soon include me. I flew east of the airport and joined the Runway XX right downwind pattern with a standard 45 degree entry. The Bonanza then announced he would not go straight in. As I was in the pattern; downwind abeam the numbers; the Bonanza flew directly across my path. I was flying south in the downwind; and he was flying east. The Bonanza crossed about 200 feet above me and this was way too close to overfly me in the pattern. I announced downwind; base; and then final as I completed my pattern. I even called a redundant short final. As I was on short final; the Bonanza cut in front of me by taking a base entry. I was only about 400 feet above the ground; on short final. He was directly in front of me turning base to very short final. I called out for him to avoid and that I would be doing a go around. The Bonanza had overshot his approach and couldn't make the turn to the runway. Instead of landing; he then started to go around; pulling up directly into my path. I made an avoidance abrupt turn to the west to avoid colliding with the Bonanza. I then flew north; away from the field; and waited for the Bonanza to rejoin the pattern to land before rejoining the pattern well behind him and eventually landing. I have never turned in another pilot for making a mistake; but three mistakes in the pattern like this. Cutting me off; who had made multiple announcements to avoid a deviant pilot like this; still did not avoid an almost mid-air collision. I highly recommend investigation of the offending pilot. Among other things; he should know better than to try to fly a straight in to an extremely busy airport like ZZZ with multiple planes in the pattern and he should know the proper procedures for entering and flying a full pattern.




Synopsis: Pilot reported that while maneuvering in the traffic pattern another aircraft flew in front of them three times; causing several NMACs.
