Best creature to use for a Saiyan inspired race’s Great Ape transformation? (Doesn’t have to be ape related.)

So how it will work is I will take the creature, apply the Kaiju subtype and any changes that come with it, and make those stats stack onto the base humanoid race’s stats for a special Change Shape functionality (or if that proves too strong, use the better of the ability scores of the base Kaiju creature, or the humanoid race after undergoing the changes into Kaiju size, and then stacking the rest of it).

I won’t use any actual Kaiju as the base creature, because I like those existing separately.

This might seem strong, but it isn’t for the players, rather the BBEG, which I plan on modeling after Vegeta (except the transformed state doesn’t necessarily have to resemble a primate). I figured it would be memorable to the players for the villain to turn into a Kaiju sized creature.

The Kaiju subtype is massive. However, I'd do the following.

I'd like to know the base race of the BBEG. If they're human, go ape. If it's like a Kitsune or something though, start with a fox or something. Alternatively, just use your BBEG's humanoid abilities and hybridize them ala Lycanthrope/Weretouched. Keep all their standard abilities and add the following.

- Kaiju subtype
- Collosal size adjustment
- 3 new major (Su) attacks. Consider a line breath weapon, some sort of AoE sphere, and maybe a missile storm type multi-target/multi-attack
- 2 primary slam or claw attacks, with a secondary tail or 2 wings, maybe a bite too if it fits the idea. Decide as well if their main weapon will grow with them, cause then all those natural attacks will be secondary and in addition to the main weapon*

That should be more than enough if the BBEG's first form was enough to give them a challenge.

* Follow Mythic Beast Shape and add the attacks from the animal to your kaiju-boss, add more with monster feats as necessary.

Admittedly... If you're race building my first thought was to give them a 1/day spell like ability for something like Form of the Dragon or something. Although Isaac kinda seemed to hit the 'ozaru' note a bit harder.

Granted I still think that the Vegeta equivalent being a half dragon with the power to transform into a full dragon is cool, but at that rate you're just fighting a dragon.

My leveled mutations don't give them full godzilla size till epic level.

If you are going to give them this at 1st level, I would take away teleportation entirely. It doesn't work in the game world, at all.
