ok simple as the title says some interesting things you have noticed while watching the TV series or purchasing the toys(don't use TFwiki its cheating).

I'll start:

Animated:

Grimlock's transformation in the Animated Toy is the exact same as the transformation on the ad bumper he appears in during G1 Madman DVD's

Transformers: RiD

the only new design on the Predicons team is Megatron the others are just copies of BW's Transmetal toys Slapper was Spittor, GasSkunk was Stinkbomb, Dark Scream was Night Glider and Sky Bite is a redco of CyberShark.

Same thing can be said about the sub group of the Preds the Decpticons the comandos are just redco/recoloured Combaticons the only original Design is Scourge and even then he steals his design from someone.

yes these may be well know but I needed something to start the thread with.
