In that case here it is:
Side-B: Machine Gun. Anthony and the other GF Soldiers are all seen using Machine Guns as their main weapons. I figure it'll work like a horizontal version of Ivysaur's Bullet Seed in Brawl.
Down-B: Overblast. Acording to Wikitroid, if you take long enough on the Bug-monster-fusion-ha thing, or do something a certain way, one of the GFs will attempt an Overblast move on the monster, only to be thrown off- most likely because they got no style
. Anthony would perform a flip jump similar in height and execution to Samus' second jump in the Smash series, and if he touches a foe during the move, he will perform a successful Overblast move, causing the foe harm, and then leap off, gaining even more height and Meteor Smashing/Spiking the foe (I'm not sure the difference between the two, as I'm a more casual Smash Player. I'm not into competetive play in most games I play) while he does it. at the peak of the jump Anthony can use his recovery move, with the loss of a use of the Overblast until he touches solid ground again. I feel this is better than the Flip-Jump in ZSS' style because for one thing, Anthony isn't as agile or flexable as Samus, especially in that armor.
Up-B: Jetback. more or less something similar to Diddy's Brawl special, but different in that it doesn't need to charge, and in turn goes about 3/4 as far as Diddy's fully charged one.
EDIT: Anthony's armor no doubt weighs him down, being far less advanced than Samus' Chozo Power Suit, making his jumps low and his falls fast, or otherwise a heavyweight character.
as for other moves, I see mostly using the Freeze Gun in Smash attacks similar Samus' own with the Power Suit on, but with different effects. for example the Side Smash should explode in ice, but in turn have less knockback and a chance of freezing at high percents. the Down Smash should be like ZSS, but with a chance of freezing at high damage with no paralysis. the Up Smash would be like Power Suit Samus', but again, lower knockback and damage in turn for freezing. for other normal attacks, Anthony should rely on Close Combat skills. From what I know, it's a tradition for the military to teach soldier some forms of hand-to-hand, blow-for-blow combat.
For his jab combo, I see the basic "Punch-punch-kick" combo used by most characters who don't use weapons.
For his Neutral B, it'd basically be as Diddy Kong himself described it: like ZSS' paralyzer except with Ice properties.
Overall I see Anthony's moveset being similar, but not nearly the same, to both Samus' Power Suit and Zero Suit forms; an even mix between the two with some creative liberties from Anthony's GF History.
His Final Smash: Fully Charged Plasma Cannon. I know it might not exactly be the ideal strength in Other M, but considering that Lucario had a freaking Kamehameha (a REAL Kamehameha, not the Aura Sphere) for his Final Smash, why the heck not? the Plasma cannon charges to full power and fires a massive and deadly green beam across the screen, similar in form and effect to Mario Finale/Zero Laser, except thinner, and only hits once, making it a little bit like Zelda/Sheik's Final Smash from Brawl. "I need to teach you a lesson about Subtlety!" will be heard when activated.
Taunts:
Up Taunt: "You got no Style!" *animation seen in OP*
Side Taunt: he moves his arm in a motion towards his direction and yells "Come on!"
Down Taunt: N/A
Easter Egg Taunt (activate by pressing left-right-left quickly, just like Star Fox): a scanner system in his helmet activates and he comments on the characters he's facing. if he scans Samus, he says, "Fancy meeting you here, Princess!"
So, what do you think?
