Can L with the Death Note stop Light Yagami who gets the Scribblenauts Notebook instead of the Death Note.

L's win Condition is to Kill Light or stop him from becoming God of the New World.

Lights win condition is to successfully become God of the New World.

Round 1. Light instead of getting the Death Note, gets the Scribblenauts Notebook instead. L has all resources he has in the anime and manga. L starts with the knowledge Scribblenauts Notebook exists, what it does, and its owner must be eliminated. Light starts with the knowledge someone who has knowledge of the Scribblenauts Notebook is chasing after him with intent to kill.

Round 2. Same as round one but L receives the Death Note. Light is aware the person who knows of the Scribblenauts Notebook has what is called a "Death Note" and knows what it does.

L's Shinigami is Ryuk, who acts in character.

For both rounds. Light cannot make himself immortal, invisible, or otherwise indestructible through Maxwell's Notebook. He also can not make himself all knowing, omni sentient, or omnipresent.
