Is Loki dead?

Oh Loki. Looks are never what they seem as the
trickster god continues to delight and deceive.
The numerous shock deaths and losses throughout
Infinity War have set fans racing for theories,
rumours and reports as they try to work out who is
gone for good and who will be somehow brought
back in Avengers 4.
A startling new theory about Loki has reignited
speculation and ties in with some very tantalising
leaks from the set of Avengers 4.
Obviously, do not read beyond this point if you have
not see Avengers 3 or do not wish to see any
spoilers.

A fantastically daring theory was tweetd by one fan
who is convinced that Loki did not die because he
had already used his magic to take the form of
another character.
Don't forget how many times he has already used
illusions to portray his own death in previous
movies, or impersonate numerous others including
his adoptive father Odin.
Josh L Dickey's tweet, picked up by Screen Rant,
said: "Loki's dagger sneak attack on Thanos was
feeble. He knew it wouldn't work. Heimdall also
knows Banner can probably survive anything
Thanos throws at him in the short-term. On Earth,
Banner is acting loopy. Can't hulk out. Deception
more useful now than force. Banner is Loki."
