6+6+6+10+25+33 = 86 dmg
Not only is the damage low but his aspd is relatively slow as well. There's also not much of an advantage to having linear AoE for his last 2 hits. Slow aspd also means you have to stay immobile longer for decent SB.
Optic Blast Barrage
6+6+6+40 = 58 dmg, AoE, Knockback
The core of Cyclop's AoE DPS. 2 Stars to deal 40 dmg mass AoE in any direction! (Bumped up to 50 dmg with his Power2); this is a healthy, conservative alternative to his Hero-Up when faced with a large group of enemies.
50 dmg, AoE, Team-Buff
Possibly the best team-buff skill in-game! Increase your entire team's Attack for only 1 Star, making Cyclops a priceless asset to any 3-4 man mission. Not only that but it deals close-range 50 dmg AoE! A great DPS alternative against mobs of weaker enemies. (Unfortunately, it also has long framerates making it unsafe & inefficient as his main-DPS Power)
Mega Optic Blast
52 dmg, linear AoE, Knockback
Not as effective as his Power1 for AoE DPS, rarely are targets put in a perfect line for you. However, it works adequately as ranged single-target DPS on Bosses since it requires very few frames compared to his Power1, giving you more mobility.
77 dmg, FS AoE, Stun
Cyclops has a pretty good Hero-Up, making him versatile as both a Support and DPS. However, in most cases you won't need to use it and are much better off using Power1 and letting your team finish the job.
How to Play:
Always keep your team buffed with Power2, by doing so you're increasing your team's DPS dramatically for very little cost. However watch out when buffing teammates, this skill has a long framerate animation that can't be cancelled leaving you open for what could be a fatal amount of time against bosses.
When encountering large groups of enemies avoid using your Hero-Up, instead, use your Power1 which deals more than adequate damage in most occasions. (Just make sure you're facing the best direction to hit as many targets as possible). If not, just use it again! In the end it's 4 stars instead of 5 for just as much DPS.
More on Power2, it's actually very good damage for 1 star (50 dmg AoE). So don't hesitate to jump into a mob of weaker enemies when you use it to buff your team, when you're done simply jump back out for Range/safety. If you're confident in not dying, (Like a Phoenix on your team who can heal) you may want to DPS with this Power often since it's more economical than his Power1.
During Boss fights you should always stay quite ranged as Cyclops since you'll be wanting to keep your team buffed with Power2 and the framerates make it rather dangerous to be close. Fortunately, his Power3 will also let you deal decent dmg from such a distance with his HU gauge.
Cyclops is one of the best "Support" character in SHSO, his Power2 is invaluable to any 3-4 player mission; dramatically increasing DPS for only 1 star. Not only that, but his Power1 provides great DPS for only 2 stars and his Power3 is adequate ranged, single-target DPS in Boss fights. If his Attack Combo was better I'd throw him up another Tier.
