Always have been a fan of Kabayas...
For this set, there's one of my favourite: Deathsaurus!
Though different from the vintage kabaya Deathy, this is still one of the best (if not the best) kabaya transformers model kits
Basically, the kabaya model kits are fun to assemble and play with. Though some of the molds are quite loose (factory default) after assembling.
I spent a couple of hours assembling these figures, inclusive of applying stickers, making sure that every single piece of plastic flash is off.
The breastforce red eagle came in Hot Spot's pack and can transform and fit into Deathsaurus' chest
The breastforce blue lion came in WFC Optimus Prime's pack.
