Considering that I-Bot's character isn't known yet
This is a pretty good interpretation of an "ARTIST- BOT"
Though to avoid the concept of everything looking like a B-Rated anime knock off.
Having P-Bot look more heroic wasn't really necessary to the portrayal of his character.
Anyone for example, can draw ANY kind of mech and add a letter "P" on his breastplate and call it P-Bot.
Same could go for A-Bot.
The original interpretations are just fine and although the reinterpretation is "cool", I don't see them becoming replacements.
Cause come on, A-Bot looks like a big Boom Box, (though similar to Soundwave) still portrays his character well.
I just don't see the portrayal in P-Bot and A-Bot to be all that representative to what they do.
I dunno, it's just my opinion.
However I-Bots character has not been intrepreted even by the staff and his is a pretty good look.
The stylish backwards cap, the spray can cannon arm, almost as if a college art student was a robot.
