Oh yeah, he looks like gandalf when fighting.
This said, I don't think the dev team took inspiration from Gandalf^^. However, they always try to take inspiration from the orignial character, or other charcacter from the same game, obviously, but I mean that every single move is inspired by an actual move of the character. Ike is really easy to breakdown (side tilt is lord basic attack, aether is aether, side B is the critical animation etc.), but what makes Robin harder is the fact that (i believe), they took inspiration from GBA and DS fire emblem games (less animations, 2d sprites etc.).
This is what I figured out for now :
- Neutral B : classic spell animation from awakening.
- Neutral B (Throron) : Ignis spell animation from awakening (maybe the critical one as well).
- up B : created for sm4sh ?
- downB : I'm sure I already saw this before, I can't remember where but I will find.
- side B : fire spell on GBA FE
- Jab 1 and 2 : Looks like the 2 slashs of the victory animation from awakening as tactician
- Jab 3 (wind) : reminds me the mages from PoR, I have to check tho.
- Jab 3 (fire) : maybe a critical on GBA ? Got it, it's the monk one i believe.
- Dash attack : when in the menu, and you check the stats of the avatar, he/she does pretty much the same animation, but hold the sword with 2 hands. It can also be a reference to the cutscene where robin stabs chrom.
- UTilt : looks like an animation of the warriors or the halbardiers in PoR or RD, when they send the ennemy in the air then jump and send them back on the ground, or more likely the ignis sword animation from awakening.
- FTilt : classic tactician sword attack.
-DTilt : created for sm4sh ?
- USmash : levin sword animation from the remake of the Marth FE on DS, probably from other FE games as well.
- FSmash :
- DSmash : maybe the tactician critical with sword ?
- NAir : maybe a victory pose or something ? I don't think it's created for sm4sh.
- UAir : created for sm4sh ?
- FAir : looks like the FSmash, probably comes from the same move, but what is this move?.
- DAir : created for sm4sh ?
- BAir : dark knight critical animation from awakening
Jumps : nothing special, and mages never jump in FE so created for sm4sh probably (the double jump forward looks like the opening animation of the tactician)
Idle : I don't remember it, have to check.
Walk : probably the same as in awakening.
Run : Robin can run ???
Taunts :
Victory :
Backward roll : dodge animation from awakening (tactician)
EDIT : wtf is wrong with my fingers, typed "awekening" every single time ><
