Indra's Mangekyo Sharingan
The anime episode showing Indra having Sasuke's eyes is a filler episode (see the list here). Trust the manga instead, which is canon. There are two reasons why the producers did changed it in the anime:


They got lazy, or they didn't have enough time to think of a unique mangekyo sharingan ability and animate the effects. So they slapped Sasuke's eyes onto Indra and called it a day.
Indra having Sasuke's eyes symbolizes how Sasuke is the reincarnation of Indra. Indra's personality, physical prowess, and intelligence were all passed down to him. So it makes sense that the MS was also passed down too.
