I have this build in mind.

DP064 - Electro - 90 points
DP002 - Headpool - 38 points
WOL021 - Lyssa Drak - 91 points
WOLR102 - Power Battery (Red Lantern Corps) - 2 points
WOLR202.02 - Axe (Red) - 6 points
WOLR202.04 - Wall (Red) - 10 points
WOLR202.06 - Decoy (Red) - 6 points
WOLR202.09 - Nurse (Red) - 10 points
WOLR202.13 - Stop Sign (Red) - 8 points
WOLR202.14 - Sniper Rifle (Red) - 6 points
WOLR302 - Red Lantern Ring - 8 points

Total point cost 275 points.

I have all but 2 word balloons "That Was Cool and Explody" & "This Besmirchment Will Not Stand".

I have 25 points to spend so I'm thinking an entity but which one would best fit this build?

Parallax on Electro. He needs the Perma-Willpower, and the Hypersonic is gravy. Plus one damage fills the bill too, with all those targets of his. Don't forget to push or Blind Al him off the first click.

I take it the push is more for parralax then electro

You're right. I was thinking of Zombie Doc Oc needing the push. In the case of Electro, he still needs the Willpower, and the Stealth isn't going to hurt anything. You can always elect to push to hit the HSS clicks on Parallax' dial, though.

Sounds like operation get my hands on a parralax is a go

Is there a particular reason you chose the red lantern power battery? If its for the poison on headpool I assume they're not for electro too so how about the red entity(dunno what it does so that can be totally useless for him) just for the stat bonus on electro.

The poison helps load z-virus tokens then electro pops off with energy explosion

really cool build. I don't think you need all the constructs you included. I don't know if you own bizzaro but you could easily shave off 25 points worth of constructs to include him and he has the monster keyword.

Well I figured 300 points 3 actions 4 clix 3 after headpool falls but I could always test out biz

I have been thinking of something similar to this with regards to both with and w/o tactics. I have two variations on w/o tactics and one with tactics.
W/O Vers. 1.0
Electro w/ Ion (for defense increase in range and increase in defense and outwit on dial one, than willpower after that too all friendly characters. Gives him Impervious and 18 Def with ESD.) 115 (90+25)
Headpool w/ Black Hand (gives an annoying combination of shape change and plus to damage on even clicks, and plus to def and "oops you missed, lose 1 def") (38+25) 63
Lyssa Drak (Maybe Black Hand on her instead just to add a secondary attacker) 91
Bill, Agent of Aim *Duh moment* 30
299 pt

W/O Tactic
Electro W/ Parallax 115
Morbius W/ Ion 185 (Also Possible to go Magneto W/ Ion and Bill)
300

Tactics
Electro W/ Parallax 115
Magneto W/ Ion 155
White Battery 2
White Ring 6
Sniper Rifle 6
Decoy 6
Crossbow 10
300 pt

But no poison spitting headpool. T-T

True but I find that the zombies getting the food tokens ends up helping more in the long run and with the white spectrum I can use a single click heal to all friendlies in 6 squares just by a power action. Plus Magneto using double TK can be really effective in moving Electro into a running shot/HSS position with a 10 range from sniper rifle.

I suppose my builds more for quick games ie throw headpool poison lightning rod energy explosion but with all the power battery's there easy to change up if things get boring

Parallax is generally the best choice to possess most characters. I'd opt for Ophidian, if you're planning on pushing Electro or Lydea.

If you forewent an Entity, you could use Bizarro @ 25 pts and add the Servant of the Great Darkness ATA to Lydea once that's legal, next week-- as you already have a Monster theme-- but you'd have to drop a Construct, though (?Decoy).
