The Tick animated series season one includes only 12 episodes in the TVD set. The release omits “The Tick vs. The Mole-Men” which I have yet to see available anywhere, anytime, anyhow. The list below is what you get with the release rather than the season as it aired.
1) Tick Vs The Idea Men
The Tick meets Arthur upon arrival in The City. Shortly thereafter they run into a criminal gang that wants to hold the city for ransom.
2) Tick Vs Chairface Chippendale
The insectile duo gets to fight alongside American Maid who’s not too happy about the team at first. They go after the biggest mastermind in town who has an unusually diabolical birthday wish and is dangerous enough to incapacitate the heroes.
3) Tick Vs Dinosaur Neil
The duo takes a vacation to an archaeological dig. There they meet Neil who is destined to turn into a giant, rampaging monster. Arthur tries to convince his sister that despite his superhero life he’s still normal. Then his partner gets swallowed by a dinosaur.
4) Tick Vs Mr Mental
Mr. Mental lures Tick to a magic show where he hypnotizes the hero. Now Tick is his patsy, and it will take the collective effort of every hero Arthur can find to stop and save his partner.
5) Tick Vs The Breadmaster
Breadmaster is attacking the city with bread bombs. Even Tick may not be strong enough to stop these attacks. For once the Human Bullet may be the hero of the day. Then again, maybe not.
6) Tick Vs El Seed
The City is under siege by plants. A giant flower wants to take the planet away from the animals and is giving plants the ability to fight back. When Tick tries to stop him El Seed’s formula turns the hero into a garden, an affliction that may turn him into a vegetable himself if he and Arthur can't get El Seed to give up the cure.
7) Tick Vs The Tick
The duo and friends head to a super hero club, but once there Arthur is sent to the sidekick hut. Tick meets Barry also calling himself the Tick. Barry wants to be the only Tick, and his tirade keeps anyone but Arthur from noticing the Evil Midnight Bomber (What Bombs At Midnight) getting ready to blow the whole place right off the map. But Arthur is just a sidekick. Why should actual heroes listen to him?
8) Tick Vs The Uncommon Cold
Thrakkorzog sends a clone Arthur after the Tick. Tick can’t tell the difference. When he himself is cloned it becomes duo against duo, but is Tick too sick from his cold to fight?
9) Tick Vs Brainchild
Young Charles is a criminal mastermind in the making. Think Dexter’s Laboratory gone bad. Tick thinks Charles just needs a hug, then Skippy the robo dog tries to eat his face.
10) Tick Vs Pineapple Pokopo
A super genius monkey falls from space near an island run by a villainous dictator. Tick, Arthur, and American Maid are sent in as secret agents, but Tick doesn’t seem to get the concept of “undercover.”
11) Tick Vs The Proto Clown
The City is deserted due to a monstrous clown. Tick makes a stand against him only to be knocked right off the planet. As he goes on a psychic journey of self-discovery the others try desperately to fend off the monster clown. They stand about as much chance as a baby slapping a brick wall.
12) Tick Vs Arthur's Bank Account
Tick is excited about the chance to face off against the legendary Terror. He goes on an upgrade binge that wipes out Arthur’s credit. Arthur is so mad he kicks Tick out sending the blue hero into a state of depressed isolation. Meanwhile Terror and his nefarious gang take over the City.
