Got some spares as part of an Ebay purchase and started tinkering.
Rampage is a Tarantulas body with movie Starscream arms and head, Unicron spikes on the head and Blackarachnia tentacles on the back.
Airazor is a repainted Blackarachnia with a sculpied head. Hands and wings are from a tiny titans Acid Storm.
Dinobot is a slightly tweaked Rattrap body with Unicron arms and a tiny titans Acid Storm head.
