n->split("Pippi Lucas Ness Travis")[2any(isinteger,sqrt([5n^2+4,5n^2-4]))+(n∈[2;[(g=golden)^i+(-g)^-i for i=1:n]])+1]

This creates an unnamed function that returns a boolean. To call it, give it a name, e.g. f=n->....

Ungolfed:

function trump(n::Integer)
    # Determine if n is a Fibonacci number by checking whether
    # 5n^2 ± 4 is a perfect square
    F = any(isinteger, sqrt([5n^2 + 4, 5n^2 - 4]))

    # Determine if n is a Lucas number by generating Lucas
    # numbers and testing for membership
    # golden is a built-in constant containing the golden ratio
    L = n ∈ [2; [golden^i + (-golden)^-i for i = 1:n]]

    # Select the appropriate Earthbound charater using array
    # indexing on a string split into an array on spaces
    return split("Pippi Lucas Ness Travis")[2F+L+1]
end
