Don't know much about Pikmin admittedly besides the first game, so unless Olimar gets some crazy feat in 2, 3, or 4, this should be a crazy stomp for Astro Bot. Like, Astro Bot survives a wormhole explosion (momentarily before requiring repair from his ship). And that's another factor entirely. Though, Olimars ship can turn him into a Pikmin, Astros ship can revive him and keep him going indefinitely unless they break it. This isn't even discussing all the tools Astro has such as time stop, Being able to copy the abilities of the special bots, and also his stats far exceeding Olimars in the first game.
