Yes, the motorbike Tarantulas seems more fitting, as it is more agile and sneaky than a big armoured personnel carrier.
(I also used to believe that Transformers have in their DNA/CNA certain types of vehicle modes by default, so that when they change bodies or rescan, they would still remain a related type of alt-mode... and Tarantulas had the motorcycle mode as a Transmetal... not because he scanned one, but because he either used to be one and it was still in his CNA, or he was built/born with that default form inside his biology.)


Rant time...

This is the second Tarantulas in 7 months (after the subscription figure)... I guess it could be put down to bad timing, but when they knew they were doing Tarantulas for next BotCon they should have released Subscription Tarantulas first so that it wasn't fresh in peoples minds with this reveal (it was the most recent subscription figure released).

Hopefully they didn't have this Tarantulas toy (and head) planned before the third subscription set was revealed, because they were soooo stubborn about giving a new head to a no-name unreleased Axellorator that didn't need it, over giving an accurate head-sculpt to the universally recognised Tarantulas (who would stand out more with the wrong head).

So far it's the dead Predacon brigade... and having earth vehicle alt-modes, it makes it hard to believe this would be set after Beast Wars.
