I didnt attend the filming of Series 7 (as spectator or roboteer), but heres my predictions.

13 Black: Is it worth gambling another go at Robot Wars?

Herbinator: Is it a robot carnivore?

Lightning: Will it strike twice?

Alien: Same design as always, not gonna pass the heats.

Hodaf the Bad: Good design, shame about the effectiveness

Thor: Will it strike everyone else?

Hydra: Might slither through

Gravity: Will it defy the laws of gravity with its flipper?

HOT TIPS FOR THE HEAT: 13 Black (seeded 7), Gravity, Lightning & Thor
