Yes it says so right there on the card, cards with name "Vehicroid" on their name and the only current one is Jumbo Drill.

the zone brings out more than the drill, vehicroids are all of the monsters fusions aswell.

Don't forget about Steam Gyroid or Ambulence Rescue Roid.

What I ment, was that the only fusion monster that can benefit from Connection Zone IS Jumbo Drill.

Steamroid, Drillroid and Submarenoid are the "MATERIAL MONSTERS" which are the ones that will be taken out by Connection Zone, but ONLY because Jumbo Drill has them listed, and because Jumbo Drill is the ONLY current "Vehicroid".

Ok, I'm getting confused with all the seemingly-conflicting answers...

1. Can you use VCZ to summon any of the Roid fusions, or only Jumbo Drill?

2. If you can bring out any of the Roid fusions, will they all get the benefits of VCZ, or is that part only for Jumbo Drill?

To sum it up...

These days in the game, Konami and UDE have pretty much abandoned the whole "in its card name" text and merely changed it to "<name here>" monster....in this case...."Vehicroid" monster IS the exact same thing as "Fusion Monster with Vehicroid in its card name".

So you can ONLY use it with Super Vehicroid - Jumbo Drill because Vehicroid Connection Zone ONLY works with "Vehicroid" Fusion Monsters which IS Fusion Monsters with "Vehicroid" in its card name.

Unless they come out with the 2nd Super Vehicroid monster that Sho used in the Anime (Super Vehicroid - Stealth Union), then Jumbo Drill is the ONLY one that will benefit from Vehicroid Connection Zone's effect.

Ah, alright, thanks for clearing that up.
