Every response I get from my friends that see Chibi-Robo for the first time: "Oh my gosh, is that a toilet?!!"
I'm just like

Your friends must be pretty dumb.

Nothing comboes into his side special right?

How do you beat the toothbrush? f***!

Edit: I swear if someone says use DI....

Relax, it has huge range/priority so it cancels a lot of projectiles. None Marth's moves outrange it (just to put in perspective how big it is) so I say you just gotta respect it. It decreases in size the longer it is out but if someone is spamming it just jump or shield. It has to move forward so shield can beat it, and he cannot go up so jumping and hitting from above works. Its weakness is that Chibi has to commit to a specific movement, so he can't do much to chase.

If you get hit by it maybe you can try to DI towards Chibi, because then you are going the opposite direction that he is hitting you. Watch out for Chibi using the toothbrush to gimp you because as stated, it goes through pretty much everything (including recovery moves).

Stupidly enough, I haven't tried just shielding through it. lol I know jumping seems to be the best way for me so far but I'll try that too. Thanks for the tip.

Maybe dodge roll in the opposite direction that the toothbrush is going, I'm sure that works too. I'd hate for you to get grabbed while trying to do something lol.

Just get over or under him depending on how high he is. It has a lot of endlag.

Chibi-Robo is dang near impossible to win with online. He's requires such precise spacing and reading of DI to land his kill-moves. But it's impossible to do that in lag. Opponents live up to 220% because only 3 moves have reasonable knockback scaling.

This is weird, even in offline matches. I understand several moves do above-average damage. Several others are difficult to land moves, though, can kill early; at 100%, or so. - But why does that everything else have to do garbage damage (averaging 7-11%) and can't even kill at 200% because of, maybe, 3 moves being powerful. Can he at least have tilts and weak aerials that KO at 150% like everyone else. This is kind of like the problem v0.9a Peach had, although, maybe not as drastic.

I've honestly been VERY surprised with Chibi-Robo. He has very few major issues, with one of the most strangely satisfying moves in the game: his side-b. The toothbrush is hilarious to KO an opponent with. Add some of the most troll-tacular moves in the game, and you have one of my favorite characters to dick around with. Oh, and did I mention his great aerials and side smash? Yeah, those are great too.

His dair is absurdly strong for something that doesn't even use a sweetspot and that grab game too deluxe. But you have to love all the sound effects on his moves they're so cute.

...I can't use him to grab Mario's Final Smash to save my life. How does every one else do it?

I think that got fixed in the patch
although I might be wrong

It did, yeah.

Chibi-Robo has one of the best recoveries in the game. He can survive at large percentages (Even one stock for the entire game) for a long amount of time. I see a nerf coming...

As well as him being heavy allows him to continue to survive with many hits.
