The combat table from the original rules had many defenses that don't appear in the 1982 edition. Some of them were completely reworked into damage-based protection (Armor, Invulnerability). Others were covered largely by the revised evasion rules (Heightened Speed, Heightened Dexterity/Agility). A few didn't make clear sense (Heightened Senses).

Some had defense scores thate were identical to existing powers: Darkness Control = Light Control; Body Power = Cybernetics (Bionics).

Special Weapon had a defense type lowered the chance to be hit HTH down to 2 (but didn't effect the base chance to be hit by other attacks retained in the second edition).

I noted the use of Phantasmal Forces as an defense for Illusions A in a House Rules post. To drum up discussion, I've placed five of the original defense types below against the attack types that moved into the original rules.

I'll post more thoughts later about my thoughts about some of these defense types. In the meantime, please add your thoughts and observations!

I don't have the original book, so I'm not voting on these, but I like the ideas above.  Especially the last one, I had totally forgotten Cloak and Dagger... Cool V&V type characters, not soo super, but a cool concept.

OK, I voted for Darkness control, I could see this almost as an Anti-light power... I've always thought it was a little weak, but this would make it as powerful as light control, which makes sense to me.

I like the teleportation/dimension power as you described, I've done a "combat teleport" invention for a teleporter before, but just allowed him to have a heightened defense type defense, subtracting from their chance to hit, but not really a defense,

As far as the others:

Body Power - I'd use the defense type that matched whatever defense the body power mimicked if possible, I don't see the need to have it's own, same for form change/transformation/mutant power.

Size Change larger and smaller have their own modifiers, the attackers range modifier is multipled (or divided) by the height factor to determine bonus (or minus) to hit, I always considered this a defense for smaller characters, and a penalty for larger ones who generally have many more hit points, kinda balanced things.

Special Vehicle would depend on the vehicles defenses if it had one. 

For special Weapon, I'd think using the alternate parrying rules would be more realistic than giving a defense for the weapon, thought I guess I could see a weapon creating a defense, but then again, I would use the defense the weapon mimicked.
