Lusios

Story
The Lusios have met The Doctor and The Voyager before, when The Doctor and The Voyager first met. One Lusios shot The Voyager causing him to regenerate. They met again many years later, this time hiding in a sewer trying to heal and invade the Earth...

Lusios in the Sewers
In the future, the Doctor, Voyager and Piper land on Earth where they discover a blob of yellow goo and a soldiers corpse in a bin. They follow it down to the sewers, when they then encounter the same soldier come out of a telephone bo. The Doctor and co realise this person was dead. The soldier then morphs into the dreaded Lusios, exclaiming "Crap!" and it then teleports away. The Doctor uses his Sonic Screwdriver to track the Lusios down and they find their base. The Lusios from an earlier adventure is on its death bed, but the Doctor stops the Lusios from taking over Earth, whilst also picking up a new companion, Ruby, played by Kian4456.

The Lusios on Mars
After the Doctor's regeneration, the Doctor and Piper receive a distress signal and they make the TARDIS home in on it. The Doctor walks over to the crashed ship and the ground begins to rumble due to the ship's engines not working. He hears Piper's scream and runs to the TARDIS. She is missing. The Doctor goes back to the ship and is greeted by two yellow Lusios. They knock him out. The Doctor then escapes the cell he was held in with Piper, where the Lusios are setting the trap. Eventually, three Lusios, two yellows and a blue Lusios surround the Doctor and Piper, leaving the Doctor with no way out other than to blow up the Lusios ship and transmat to the TARDIS. This upsets Piper, and the Doctor begins to take her home. A Lusios then exclaims "Crap!" once again, and it gets blown up with the ship.
