TV THIS WEEK: Krypton returns, new Agents of S.H.I.E.L.D., iZombie and more

The Arrowverse might be taking the summer off, but SYFY's DC prequel series Krypton is back and ready to save the universe for the next couple months. Oh, and the Agents of S.H.I.E.L.D. are still taking care of business in deep space.

Krpyton's second season premiere is the big story this week, as the pre-Superman tale looks to introduce Lobo to the mix as Zod fully takes control of the past. ABC has a new Marvel's Agents of S.H.I.E.L.D. with pretty much everyone in peril, and AMC is keeping things scary with Fear the Walking Dead and NOS4A2. The CW also has The 100 and iZombie in service, and CBS's summer adventure series Blood & Treasure is all new. Freeform also has some mermaid drama with a new episode of Siren.

Check out our full rundown below and let us know what you'll be watching this week.
