Ideas ahoy.

First up, I Still rather like that crouch you have on the other gif, thought I would point it out, its really good, but if you keep that crouch, at least change the head, since it has the same problem the standing head had.( lack of depth)


now the following is only suggestions:


From buuyu retsuden there are some moves that are classic

Elbow slide: freeza slides forward gracefully, then extending his elbow almost carelessly his hand on his chin as he does it, this hits heavy using the velocity to push the opponent, the move is open for the first frame as he slides only hitting in the end.
Tail flip- freeza jumps and spins once with his tail going down in an arc, hitting anyone standing ( but not crouching)
straight headbutt: freeza leaps forward head first, if he connects, the opponent is sent flying
meteo attack: freeza kicks the opponent in the chest sending them upwards, he teleports up where he slaps them down with his tail, as the opponent is rebouncing in the floor he lands and uses the headbutt above to finish the attack sending them flying.


INTROS:
Freeza arrny grunts  ( do like, one body, with the animation of shooting , flying ( one frame) and the animation of falling dead, several heads can then be done to make them seem like many   ) they point at the enemy and shout threats, a big blast of energy falls from above blowing them up freeza lands from above.

One army grunt pointing his fist, freeza teleports behind him, raises his hand to his head and a short beam comes out, he falls down headless as freeza laughs.

Freeza sitting in the ground with a skull on his hand, he crushes it with his hand and rises to his feet.

tiny freeza with several army grunts around him as if protecting him, freeza goes through his transformations but the moment he flares up all his minions blow away.

freeza floating with his arms widespread, graciously floats down and gives a small bow.

Freeza furious, muscles bulging ( like in his 100 percent mode, really huge) slowly calms down, thins down and smirks

hooded freeza, his eyes shine red and he eyelasers his hood off, making him burn.

The whole stage is littered with defeated army grunts, one last one stands shaking, freeza teleports behind him, and punches through his chest

Freeza sitting in the ground, his tail waving like a cat's tail.

raise one finger and starts doing the death ball animation as he slowly rises, the ball growing and growing

yawns

He spits angrily to the opponent, then points his hand to the distance, gestures and a giant rock falls on top of the opponent, burying them ( this could also be a move)

His father falls out of the sky besides him and they both share a laugh.


for his emotion system, where he charges up hate for the death ball, he could gain meter from hitting the opponent or taunting him instead of actually "charging".   He could also have moves that are only avaliable in this form.

goku has the kaioken as a move that can be powered up by genkidama for a finisher, with other finishers if he doesnt have genkidama energy for it, freeza could have a similar move, a hyper combo that finishes in several ways:

A Firing squad appears to attack his opponent as freeza laughs it up
A squad of minions beat up the opponent phisically
( maybe both at the same time?)

The coup de grace would be that freeza would be able of finishing with a deathballl that engulfs everyone and kills them all ( maybe a couple are alive after and running for their lives, think bardock and planet vegeta)
