Ah, thanks for showing and clearing this uncertainty for me! So happy to see Bowser Jr. actually has so many good things going for him since he was one of the characters I used from time to time. I hope he stays far away from being the worst~
I wonder what got you picking ROB and Olimar in the first place. Are hold nostalgia over that ROB toy years back? Are you a big fan of the Pikmin series? Do you just like how they play in Smash in general? Or maybe you prefer the more uncommon choices? I certainly rarely seen anyone picking Olimar online in Smash 4. There were some ROBs here and there, but still a bit of a rarity. Piranha Plant does look like a whole lot of fun though!
And yeah, I'll be sticking with Pikachu as one of my most picked characters. That is...unless a certain cute yellow feathered bird shows up~
For ROB, I'm not sure why I picked him. I'm far too young to have ever owned a ROB and my only prior experience of him was through Mario Kart DS. For whatever reason I started playing as him in Brawl then kept it up throughout Smash 4 because I liked his playstyle, his design and his personality (as much as you can say that for a robot).
For Olimar, it's definitely because I'm a fan of Pikmin: Pikmin 2 is one of my favourite games ever. I was really happy when he made it into Brawl and stuck with him as a main. I like his playstyle though at the time I had no idea that he was top tier in Brawl. I think I just generally enjoy characters who have good range and projectile options. That's part of the reason why I'm really looking forward to Piranha Plant, who could have some crazy edgeguarding options.
As for you sticking with Pikachu, have you ever been tempted by Pichu or are you not really interested? And while we don't know who our Square Enix rep will be, I can almost see Chocobo happening because hardly anyone is expecting them, and Sakurai is always surprising us...
