A CBBC children's series from Creator/RussellTDavies and PhilFord, and something of a SpiritualSuccessor to ''Series/TheSarahJaneAdventures''.

The premise is ExactlyWhatItSaysOnTheTin - the evil magic-eating Nekross have come to Earth, the last source of magic in the entire universe, to seek new sources of magic to consume. They are opposed by young wizard Tom, his {{Muggle}} friend Benny, and Tom's eccentric grandmother Ursula.
----
!!This show provides examples of:
* AdiposeRex: The Nekross King - we only ever see his vast head.
* ArtisticLicenseAstronomy: A ship hiding behind the moon wouldn't be in geostationary orbit. Selenostationary, maybe.
* BadassGay: Benny
* CatchPhrase: '''THE NECROSS SHALL FEAST!!!'''
* CoveredInGunge: Aliens that explode in showers of orange goo when killed? Check.
* DownerEnding: Stories such as ''100 Wizards'' and ''The Thirteenth Floor'' must be viewed with tissues at hand
* EnemyMine: The heroes and Varg team up after Tom and Lexi are kidnapped:
--> '''[[{{BRIANBLESSED}} Nekross King]]:''' A COALITION?!?
--> '''Varg:''' [[WhatDoYouMeanItsNotPolitical That will end, as all coalitions must.]]
* EnergyAbsorption: The Nekross can't be harmed by magic; rather, they feed on it.
* InsistentTerminology:
** Tom is a ''wizard'', not a magician.
** Randal Moon is a ''hob''goblin.
** It's ''[[BlackMagic Grim]]'' [[BlackMagic Magic]].
* InterspeciesRomance: Tom and Lexi. They go all the way in one story.
* KillerRabbit: The Grazlak.
* LargeHam: Given that the King of the Nekross is voiced by {{BRIANBLESSED}}, it's only to be expected.
* {{Mana}}: Wizards can cast at most three spells in a day...
** RegeneratingMana: ... and their magic is recharged at sunrise.
* PortalDoor: With the appropriate incantations, the door that normally leads to Ursula's downstairs lavatory gives access to her magical chamber.
* PrecisionFStrike: In ''Grazlax Attacks''.
--> '''Tom (to Benny)''': You really are a dick!
* RuleOfThree: Magic runs on it.
* TeleportInterdiction: Magical teleportation can't breach the hull of the Nekross' ship. Justified, since they feed on magic.
* TonightSomeoneKisses: Tom and Lexi in ''The Thirteenth Floor''
* SpiritualSuccessor: To ''Series/TheSarahJaneAdventures''. Some SJA episodes were even rewritten as Wizards episodes after [[ActorExistenceFailure Sarah Jane's actress passed away]].
